If there are no laws against this sort of depraved manipulation, there should be. It seems to me that she’s at least an accessory to murder.
If you make a law against this, what is to stop the government from banning guns, as they are a tool used in suicides.
Saying that someone else is responsible for a suicide due to speech, is saying that a gun is responsible for a suicide because a bullet was used.
it takes the responsibility for personal choice away from the person who commits suicide to someone else, be it by speech or a bullet..
